How to Harvest, Dry & Use Calendula Flowers

Calendula is officially one of my favourite flowers to grow in the garden. I could probably say that about all my flowers – I do love them all! – but calendula definitely deserves its place in the top 5. It is beautiful, easy to grow, has a long blooming season, is easy to save seeds from, and contains medicinal qualities! Here’s how to harvest and dry calendula for use in recipes.

I’ve used calendula in the past to make calendula oil, shortbread and calendula cream, but that was from store-bought, pre-dried calendula petals. I haven’t used calendula that I’ve grown, harvested and dried in recipes or DIY products yet, so this is my first time using homegrown calendula!

It’s such a money saver to grow and dry your own calendula, as the petals – especially good quality and organic – can be fairly pricey. What’s more, they are just beautiful to have growing in the garden, and come in different shades of orange and yellow!

Tinctures, teas, creams, poultices, salves/balms, and other creations can be made using herbs and flowers from your garden.

When drying calendula flowers, you can either pull the petals off and dry them that way, or dry the whole flower.

How to Dry Calendula Flowers

Here’s how to dry calendula at home:

1. Harvest the Flowers

First, you want to collect the calendula blossoms you’ll be using.

The best time to harvest calendula flowers is in the morning, after the dew has dried. They’re fresh, opening towards the sun, and don’t have wet petals. You also want to collect the blossoms when they’re half-open, because soon after this point, they begin to open more, and move past their prime medicinal time, where the petals begin to wither.

To harvest; gently snip off the flower head at the top of the stalk using scissors. You can also collect the leaves for use in recipes, as they contain much of the same medicinal qualities as the flowers. Trim back the stem that remains on the plant once you’ve collected the flower, so that it doesn’t start to rot.

Ensure you trim the stem after collecting the calendula flower(s) to prevent it rotting.

Now, if you don’t harvest the flower blooms, they’ll simply die back on their own, and go to seed. If you want to collect the seeds to plant next season, monitor the flowers and collect the ripe seeds when they’ve turned brown, not green. Pop seeds into a brown paper bag, write the date and what’s inside on the bag, then they’re ready to store! Hang the brown paper bag somewhere out of the way, preferably in a dark, dry place at room temperature.

2. Dry the Flowers

There are many ways to do this, but the basic principle is to provide good airflow/circulation as well as protect the petals from too much sunlight. Do not wash the flower heads. Spread them out on a ventilated surface: cheesecloth, screen or a mesh of some kind. You can even build drying screens from light timber with a screen tied between ― simply make a frame and staple the screen to it (you can even make multiple screen layers to create more space to dry the petals).

Another method is to use a dehydrator. This is my preferred method for drying herbs and flowers from the garden, as it means I can do it indoors. Dehydrate flowers at a temperature of around 32°C-35°C (90°F-95°F). You don’t want to expose these flowers to too much direct heat, as it can reduce a lot of their health properties.

To dry; spread out the heads (or just the petals) face down on a clean dishtowel, cheesecloth, sheet, newspaper, old window screen stretched between two chairs, or dehydrator. Oven drying is not recommended. If using a dehydrator, set the temperature to around 32°C-35°C (90°F-95°F). If air drying, turn them over every so often, and make sure to keep them out of direct sunlight.

Before and after drying the calendula petals; I used a dehydrator to dry out the petals.

3. Store the Flowers

Wait until they’re completely dry before storing, otherwise they will go mouldy when stored. To tell whether they’re finished, look out for the following signs:

  • They should be fragile, crispy and very dry; like crepe paper.

The green part, the flower head dries at a much slower rate than the petals. So, if you’re going to store the heads whole, then allow extra time for the green parts to dry too.

To store; keep the dried calendula in glass jars with airtight seals in a dark cupboard or pantry. Label and date all your flowers, then they’re ready for use in recipes and DIY’s!

I store my calendula petals in a glass jar in my pantry, out of direct sunlight, ready to use for when I want to make calendula oil (or other recipes).

As always, this is not personal medical advice and we recommend that you talk with your doctor before trying or using any new products. It’s important to check with a doctor before taking this or any new product, especially if taking any other medicine or supplement or if pregnant or nursing.
